Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The core of the application is to provide a remote upgrading method, which is used for solving the problem that the single-point OTA technology cannot meet the requirement of synchronous and rapid upgrading of the firmware of the large-scale terminal equipment due to high repeatability, high time consumption and long-term instability of the operation.

The present application will be described in detail with reference to the accompanying drawings and examples.

The terminal equipment of the application can be a server, and can also be a system in which the server and a local terminal are matched with each other. Accordingly, each part, for example, each unit, sub-unit, module, and sub-module, included in the terminal device of the present application may be all disposed in the server, or may be disposed in the server and the local terminal, respectively.

Further, the server may be hardware or software. When the server is hardware, it may be implemented as a distributed server cluster formed by multiple servers, or may be implemented as a single server. When the server is software, it may be implemented as a plurality of software or software modules, for example, software or software modules for providing distributed servers, or as a single software or software module, and is not limited herein. In some possible implementations, the remote upgrade method of the embodiments of the present application may be implemented by a processor calling computer-readable instructions stored in a memory. Specifically, the terminal device in the embodiment of the present application may specifically be a gateway end, and the following description takes the gateway end as a protection subject of the remote upgrade method.

As shown in fig. 1, fig. 1 is a schematic flow diagram of a first embodiment of a remote upgrade method provided by the present application, and the specific steps of the remote upgrade method according to the embodiment of the present application are as follows:

step S11: and responding to the remote upgrading instruction, and acquiring a remote upgrading data packet.

In the embodiment of the application, a user can initiate an upgrading request to the cloud end through the mobile client, and the cloud end receives an instruction of the upgrading request and then issues a remote upgrading instruction to the gateway end. The gateway end can respond to the remote upgrading instruction of the cloud end to obtain a remote upgrading data packet required by the equipment end.

Step S12: and acquiring a device sequence group, wherein the device sequence group comprises a plurality of terminal devices.

In the embodiment of the application, a remote upgrade data packet can be issued to an equipment end by adopting a multicast technology for a subsequent gateway end, so that the equipment end can be upgraded by using the remote upgrade data packet. The gateway terminal may obtain a device sequence group, where the device sequence group includes a plurality of terminal devices.

It should be noted that the multicast technology refers to a network communication in which a single sender corresponds to multiple receivers. In the multicast technology, by transmitting a single information stream to a plurality of receivers, the network communication flow under the condition that the plurality of receivers listen to or view the same resource at the same time can be reduced. In the embodiment of the application, the gateway can issue the remote upgrade data packet to the device by using a multicast technology.

Specifically, the gateway can establish a memory management linked list for the device sequence to perform group management on the devices. In the embodiments of the present application, the number of groups is not limited, and for example, the number of groups may be one group, or may be two or more groups.

In other embodiments, the device sequence group may further include a plurality of routers, wherein each router is communicatively connected to at least one terminal device. As can be understood, for the device end closer to the gateway end, the gateway end can directly perform communication connection with the device end; however, for the device end far away from the gateway end, in general, the device end needs to establish communication connection with the router first, and then perform communication connection with the gateway end through the router. Therefore, the gateway acquires the equipment sequence comprising a plurality of routers so as to realize communication with the equipment end with a longer distance, and further realize grouping.

Preferably, in order to enable the terminal device to be upgraded to enter into the group, in other embodiments, the gateway may further obtain a device management queue, where the device management queue includes a plurality of terminal devices to be grouped. Further, the gateway terminal traverses the terminal devices in the device management queue in a semaphore blocking waiting manner to add the terminal devices to the device sequence group. And for the terminal equipment which fails to enter the group, the gateway terminal traverses the terminal equipment which fails to join the equipment sequence group again until the traversal times reach the preset times.

It should be noted that the semaphore block waiting is a state where a program waits for a message, and the mechanism is a semaphore block waiting mechanism if a waiter cannot do anything other than waiting for the message in the whole waiting process. If present in a program, that is, the program is always blocked from further execution at the function call. In the embodiment of the present application, a plurality of device sides can only wait for traversal of the gateway side in sequence to join the group. If the equipment end fails to enter the group, the gateway end traverses the equipment end again to enable the equipment end to join the group.

Further, the preset number of traversal is not limited in the present application, for example, the number of traversal may be three, in this embodiment of the present application, for an equipment end that has failed to enter a group after traversing three times through a gateway end, the gateway end does not perform traversal any more, and considers that the equipment end fails to enter the group.

Preferably, in other embodiments, the gateway can create the device sequence group based on the group device instruction after responding to the group setting instruction of the cloud.

Specifically, the gateway end can actively report the respective remote upgrade attributes of the gateway end and the device end to the cloud end every time the gateway end is powered on again, and the attributes indicate whether the gateway end and the device end have the remote upgrade capability. The cloud terminal sends a group setting instruction to the gateway terminal after receiving the respective remote upgrading attributes of the gateway terminal and the equipment terminal sent by the gateway terminal, wherein the group comprises a plurality of equipment terminals meeting the remote upgrading capability.

Preferably, in order to enable the user to view the grouping progress of the device side through the mobile client. The gateway terminal can also obtain the grouping progress of creating the equipment sequence group, and the grouping progress is sent to the mobile client so that the mobile client can visualize the grouping progress.

Specifically, the gateway terminal can start the report timer of the group entry progress so as to proportionally display the group entry progress at the mobile client terminal, thereby enriching man-machine interaction. After the device end group entering action starts, the gateway end group entering progress reporting timer is started immediately, and the success or failure result of the group entering is reported to the cloud periodically, so that the pressure of the cloud for frequently receiving and sending data is relieved.

Step S13: and issuing the remote upgrading data packet to a plurality of terminal equipment in the equipment sequence group by adopting a multicast technology so that the plurality of terminal equipment are upgraded by utilizing the remote upgrading data packet.

In the embodiment of the application, after acquiring the device sequence group including the plurality of terminal devices, the gateway issues the remote upgrade data packet to the plurality of terminal devices in the device sequence group by using a multicast technology, so that the plurality of terminal devices are upgraded by using the remote upgrade data packet.

Based on the above embodiment, the gateway may also issue a remote upgrade data packet to the router in the device sequence group by using a multicast technology, so as to forward the remote upgrade data packet to the plurality of terminal devices through the router, thereby implementing the upgrade of the plurality of terminal devices by using the remote upgrade data packet.

Specifically, the gateway may first obtain communication information of a plurality of terminal devices in the device sequence group, then distribute packet sending time of the terminal devices according to the communication information of the device terminal by using a multicast technology, and finally issue a remote upgrade data packet to the terminal devices according to the packet sending time of the terminal devices.

It can be understood that when the gateway and the device communicate with each other, the two devices may interact with each other frequently through heartbeats, and meanwhile, since the gateway continuously broadcasts and sends the remote upgrade data packet to the device, and a large amount of signal energy of the gateway data source and the multicast data are forwarded between the routers at high frequency, it is very easy to encounter a CCA (Clear Channel Assessment) threshold problem of a collision avoidance mechanism, which causes the remote upgrade data packet to be sent unsuccessfully and lost by the IEEE 802.15.4 physical layer. Therefore, in order to utilize the occupied channel bandwidth to the maximum extent, analyze a large amount of firmware upgrading experiment frequency spectrums and the successful packet receiving rate of the equipment end, the gateway end can obtain the optimal packet sending time of the terminal equipment and send packets to the terminal equipment according to the communication information of the equipment end.

Note that CCA (Clear Channel Assessment) is a Channel Assessment. In a wireless communication system, before an apparatus needs to transmit data on a certain frequency channel, the apparatus firstly receives the data on the frequency channel, and if a given time passes, no other apparatus is found to transmit data on the frequency channel, the apparatus starts to transmit; if other devices are found to be transmitting data, the process is retried again after randomly avoiding for a period of time. The method can effectively avoid collisions on the wireless channel, also called carrier frequency interception multiple access with collision avoidance. In the embodiment of the application, if the transmission frequency from the gateway to the device exceeds the CCA threshold, collision of wireless channels is very likely to occur, and further, the remote upgrade data packet is failed to be transmitted and lost.

Therefore, in order to prevent the situation of data packet transmission failure caused by the CCA threshold problem, the gateway may obtain the optimal packet sending time of the terminal device according to the communication information of the device, and send the packet to the terminal device.

Preferably, the gateway end may adopt a dynamic interval time allocation method to circumvent this problem. The dynamic interval time allocation method is to adjust the communication time in the state when a line of a certain system works online, that is, communication is performed, so as to avoid the situation that the uplink and downlink traffic demands among a plurality of lines conflict. In the embodiment of the application, the gateway can adjust the packet sending time by adopting a dynamic interval time allocation method according to the communication information of the equipment end so as to send the packet to the equipment end according to the optimal packet sending time, thereby avoiding the condition of data packet sending failure caused by the CCA threshold problem.

It should be noted that the remote upgrade data packet is sent from the cloud to the gateway, and the gateway performs local storage operation on the remote upgrade data packet and then sends the remote upgrade data packet to the device.

Preferably, the gateway may analyze the url (uniform resource locator) link according to the remote upgrade data packet sent by the cloud and store the url link. Further, the gateway terminal can also perform local verification operation on the stored remote upgrade data packet.

Preferably, after the gateway end completes the local verification operation of the remote upgrade data packet, the gateway end may further issue a remote upgrade notification to a plurality of terminal devices in the device sequence group, so that the plurality of terminal devices enter a remote upgrade state.

It should be noted that, in the present application, information included in the remote upgrade notification is not limited, and may be, for example, upgrade mode information, a multicast protocol version, remote upgrade firmware key information, a multi-bit enable bit, and the like.

On the basis of the above embodiment, the gateway terminal issues the remote upgrade notification to the device terminals in the device sequence group, so that after the terminal devices enter the remote upgrade state, the gateway terminal can further send the remote upgrade data packet to the terminal devices. Because it can not be guaranteed that all terminal devices can receive the complete remote upgrade data packet, the remote upgrade data packet can be identified, so that the terminal devices can search missing data packets.

Preferably, the gateway end may read a locally stored remote upgrade data packet to construct load content, and then send the remote upgrade data packet to the device end. Because the maximum tolerance of a single remote upgrade data packet is 128B, the length of the APS frame header data is removed, the effective load 60B in the load content is adopted each time, and meanwhile, the information such as the control instruction type, the sub-packet equipment serial number, the data check bit and the like is added, so that the remote upgrade data packet is issued to the terminal equipment in the equipment sequence group by adopting the multicast technology.

Further, as shown in fig. 2, fig. 2 is a schematic flowchart of a second embodiment of the remote upgrade method provided in the present application. After the gateway sends the remote upgrade data packet to a plurality of terminal devices in the device sequence group by using a multicast technology, the gateway can further send a missing query instruction to the terminal devices to query whether the device fails to be upgraded.

Step S21: and issuing a missing query instruction to a plurality of terminal devices.

In the embodiment of the application, the gateway terminal issues a missing query instruction to a plurality of terminal devices to query whether the device terminal fails to be upgraded.

Step S22: and acquiring missing sub-data packet serial numbers uploaded by a plurality of terminal devices based on the missing query instruction.

In the embodiment of the application, for the device side which fails to be upgraded, the missing sub-packet serial number of the device side can be uploaded to the gateway side based on the missing query instruction.

Step S23: and transmitting the sub-data packet corresponding to the sub-data packet serial number to a plurality of terminal devices by adopting a multicast technology.

In the embodiment of the application, the gateway obtains the missing sub-packet serial numbers respectively uploaded by the terminal devices which fail to upgrade, and issues the sub-packets corresponding to the missing sub-packet serial numbers to the device terminals in the device sequence group by using a multicast technology.

Preferably, all the equipment terminals in the group receive the sub-data packets issued by the gateway terminal and judge whether the equipment terminals are missing, and for the equipment terminals missing the sub-data packets, the missing data packets are written into the cache; and for the device end which does not lack the sub-data packets, namely is upgraded successfully, discarding the data packets received later.

It can be understood that the gateway performs the report supplementing operation on the device side by using the multicast packet supplementing mode, the gateway presents an exponential decreasing trend for the number of traversed device packet supplementing, and meanwhile, the traversing, inquiring, responding and packet supplementing speed of the gateway is faster and faster, so that the execution speed of the group-rising data packet is greatly improved.

Preferably, when the gateway obtains the missing sub-packet serial numbers uploaded by the terminal device that fails to upgrade, the gateway is limited to the maximum 128B data tolerance of its single transmission, and the gateway may communicate with the device end in a differential cyclic response mode using the MF flag bit.

The MF flag bit is the lowest bit in the flag field in data transmission, and by setting the MF flag bit instead of the entire flag field, the receiver of the data can know the entire flag field where the flag bit is located, that is, the arrival time of the data packet, only through the MF flag bit.

Preferably, in order to reduce the task overhead of dynamic memory allocation in the whole transmission process, the gateway end may use a static memory allocation mode to record the missing sub-packet sequence of the device end, and may use a global offset as a supplementary packet identifier.

It should be noted that, the static memory allocation is to allocate the required memory space for the gateway automatically by the system, and when the data packet is used up in the active domain, the system will automatically release the occupied memory space for the gateway; the global offset is an analysis means of manual encryption, and the task overhead of dynamic memory allocation in the whole transmission process can be effectively reduced by setting a static memory allocation mode and a global offset means.

Referring to fig. 3, fig. 3 is a schematic view of a work flow of the remote upgrade system provided in the present application. As shown in fig. 3, a user sends an upgrade request to the cloud terminal through the mobile client, and the cloud terminal receives an instruction of the upgrade request and issues a notification of group establishment to the gateway terminal. And the gateway receives the group establishing instruction of the cloud and issues the group establishing instruction to the equipment end so as to establish the equipment end group, and the result is displayed to the user in a visualized manner through the mobile client.

Further, the gateway receives a remote upgrade data packet issued by the cloud, analyzes the remote upgrade data packet, and performs local cache operation and verification operation on the remote upgrade data packet through the analyzed url link.

Further, the gateway end broadcasts the remote upgrade data packet to the equipment end to realize the remote upgrade of the equipment end. The gateway end can start a group upgrade progress reporting timer, and the group upgrade progress and the required remaining time of the equipment end are displayed in a proportional mode through the mobile client. After the equipment end cluster is upgraded, the gateway end can further issue a missing query instruction to the terminal equipment to query whether the equipment end fails to be upgraded. All the equipment terminals in the group receive the sub-data packets issued by the gateway terminal and judge whether the equipment terminals are missing, and for the equipment terminals missing the sub-data packets, the missing data packets are written into a cache; and for the device end which does not lack the sub-data packets, namely is upgraded successfully, discarding the data packets received later. Furthermore, the gateway traverses and reports the current firmware versions of all the devices, so that the upgrading structure of the device side can be judged after cloud background inspection, and meanwhile, the result can be displayed at the mobile client side, and the user can conveniently check the result.

Further, after the group upgrading process is finished, the gateway end can report a finishing mark to the cloud end, the cloud end receives the finishing mark instruction and then conducts operations of group breaking and resource releasing, and the mobile client end is informed to conduct other operations for the user.

The remote upgrading method can be used for remotely upgrading large-scale terminal equipment in a centralized mode, the iteration threshold of product firmware of Zigbee nodes used in a large-scale mode by manual operation is reduced, and meanwhile, the CCA threshold collision problem caused in the packet sending process of the gateway end and the upgrading failure problem caused by the fact that the equipment end is influenced by network environment interference are avoided in a hundred percent mode by adopting an expected query response group packet supplementing mode. The gateway end communicates with the device end by using a multicast technology, and can perform data management on a plurality of devices needing group upgrading in a targeted manner. The realization of the multiple optimization modes greatly shortens the total time of successful remote upgrading of all equipment under large-scale terminal equipment, improves the stability of remote upgrading of the large-scale equipment, and greatly improves the control of the large-scale equipment, the reliability of data reporting and other performances.

Further, the remote upgrade system may further include a mobile client 31 and a cloud 32.

In the embodiment of the present application, a user sends an upgrade request to the cloud end 32 through the mobile client 31, and the cloud end 32 receives an instruction of the upgrade request and sends a remote upgrade instruction to the gateway end 33. The gateway 33 responds to the remote upgrade instruction of the cloud 32, and obtains a remote upgrade data packet for the device 34 to upgrade. In addition, the gateway 33 obtains and labels a device sequence group through the device 34, where the device sequence group includes a plurality of device terminals 34. Further, the gateway 33 issues a remote upgrade data packet to a plurality of device terminals 34 in the device sequence group by using a multicast technology, so that the device terminals 34 perform upgrade by using the remote upgrade data packet.

Further, the gateway 33 may issue a missing query instruction to the device 34 to query whether the device 34 fails to upgrade. All the device ends 34 in the group receive the sub-data packets issued by the gateway end 33 and judge whether the device ends themselves are missing, and for the device end 34 missing the sub-data packet, the missing data packet is written into the cache; for the device end 34 that does not lack the sub-packets, i.e. that is successfully upgraded, the later received data packets are discarded.
